The series delivers intermittent torque of 201-300 lb-ft and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Shift is air shift. Output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Tapered bearings provide load-bearing capability across utility truck, dump truck, and vocational equipment applications.
